00:00:17.318 --> 00:00:19.952
Stroke happens when blood
flow doesn't get to brain

2
00:00:19.987 --> 00:00:22.621
cells and they die,
causing a loss of the

3
00:00:22.656 --> 00:00:25.991
bodily function
those cells support.

4
00:00:26.027 --> 00:00:28.494
Most strokes are ischemic.

5
00:00:28.529 --> 00:00:31.397
An ischemic stroke occurs
when an artery becomes

6
00:00:31.432 --> 00:00:35.200
blocked, keeping brain
cells from getting oxygen.

7
00:00:35.236 --> 00:00:38.737
Those cells weaken and
die within minutes.

8
00:00:38.773 --> 00:00:41.840
Time lost is brain lost.

9
00:00:41.876 --> 00:00:43.876
It's important to
get medical attention

10
00:00:43.911 --> 00:00:45.177
immediately.

11
00:00:45.212 --> 00:00:48.180
Call 911 if you or someone
you know may be having a

12
00:00:48.215 --> 00:00:50.082
stroke.

13
00:00:50.117 --> 00:00:52.384
Ischemic strokes are
commonly caused by a

14
00:00:52.420 --> 00:00:54.987
disease called
atherosclerosis, when

15
00:00:55.022 --> 00:00:57.489
plaque made up of
cholesterol, fat, and

16
00:00:57.525 --> 00:01:00.426
other substances, builds
up in the inner lining of

17
00:01:00.461 --> 00:01:01.960
an artery.

18
00:01:01.996 --> 00:01:04.696
This can make the vessel
narrow, limiting blood

19
00:01:04.732 --> 00:01:06.899
flow and making it easier
for blood clots to form.

20
00:01:06.934 --> 00:01:11.537
Blood clots may grow large
enough to block a narrowed

21
00:01:11.572 --> 00:01:14.473
vessel or pieces of the
clot make break off and

22
00:01:14.508 --> 00:01:16.775
travel to a smaller
vessel, where it gets

23
00:01:16.811 --> 00:01:20.946
stuck and stops blood
from getting through.

24
00:01:20.981 --> 00:01:23.382
If you think you or
another person are having

25
00:01:23.417 --> 00:01:26.452
a stroke, no matter what
type, it's very important

26
00:01:26.487 --> 00:01:29.188
to get help quickly so
emergency medical teams

27
00:01:29.223 --> 00:01:31.557
can tell what kind of
stroke you're having and

28
00:01:31.592 --> 00:01:35.594
the right type of
treatment can begin.

29
00:01:35.629 --> 00:01:39.565
Commonly used diagnostic
tests to figure this out

30
00:01:39.600 --> 00:01:43.035
allow doctors to
see your brain.

31
00:01:43.070 --> 00:01:47.539
This might include a CT
or CAT scan, or an MRI.

32
00:01:47.575 --> 00:01:50.109
Both of these specialized
brain scans can help

33
00:01:50.144 --> 00:01:52.444
doctors make the right
treatment decision

34
00:01:52.480 --> 00:01:54.480
quickly.

35
00:01:54.515 --> 00:01:56.815
Treatment for ischemic
stroke is aimed at getting

36
00:01:56.851 --> 00:01:59.418
rid of the blockage and
getting blood flowing to

37
00:01:59.453 --> 00:02:01.253
the brain again.

38
00:02:01.288 --> 00:02:03.188
When someone having
a stroke gets to the

39
00:02:03.224 --> 00:02:06.291
hospital in time, they may
be able to receive a drug

40
00:02:06.327 --> 00:02:09.795
to dissolve the clot
and restore blood flow.

41
00:02:09.830 --> 00:02:12.998
When given within three to
four and a half hours from

42
00:02:13.033 --> 00:02:15.234
the first signs of
ischemic stroke, this

43
00:02:15.269 --> 00:02:17.736
treatment can limit the
degree of brain injury and

44
00:02:17.771 --> 00:02:20.939
make recovery easier.

45
00:02:20.975 --> 00:02:23.275
For some people,
mechanical thrombectomy

46
00:02:23.310 --> 00:02:25.511
may also be recommended.

47
00:02:25.546 --> 00:02:28.947
In this procedure, doctors
use a catheter to thread a

48
00:02:28.983 --> 00:02:32.251
small wire cage through an
artery in the groin to the

49
00:02:32.286 --> 00:02:34.653
artery in the brain
with the blockage.

50
00:02:34.688 --> 00:02:37.856
The doctor opens the wire
cage, grabs and removes

51
00:02:37.892 --> 00:02:39.958
the clot.

52
00:02:39.994 --> 00:02:42.327
If thrombectomy is
recommended, it should

53
00:02:42.363 --> 00:02:44.997
typically be done within
six hours of the first

54
00:02:45.032 --> 00:02:47.699
stroke symptoms,
though sometimes can be

55
00:02:47.735 --> 00:02:50.669
beneficial up to 24 hours
after the first signs of

56
00:02:50.704 --> 00:02:52.504
stroke.

57
00:02:52.540 --> 00:02:56.408
Know these common symptoms
of stroke and call 911 if

58
00:02:56.443 --> 00:02:59.411
you or someone near you
is having one or more of

59
00:02:59.446 --> 00:03:00.979
them:

60
00:03:01.015 --> 00:03:04.449
Sudden numbness or
weakness of face, arm, or

61
00:03:04.485 --> 00:03:07.886
leg, especially on
one side of the body

62
00:03:07.922 --> 00:03:10.956
Sudden confusion, trouble
speaking or understanding

63
00:03:10.991 --> 00:03:12.724
speech

64
00:03:12.760 --> 00:03:16.695
Sudden trouble seeing
in one or both eyes

65
00:03:16.730 --> 00:03:20.499
Sudden trouble walking,
dizziness, loss of balance

66
00:03:20.534 --> 00:03:22.267
or coordination

67
00:03:22.303 --> 00:03:26.104
Sudden severe headache
with no known cause

68
00:03:26.140 --> 00:03:28.807
You can also use the
letters in F.A.S.T.

69
00:03:28.842 --> 00:03:30.976
to spot stroke signs:

70
00:03:31.011 --> 00:03:35.614
F - Face drooping Does one
side of the face droop or

71
00:03:35.649 --> 00:03:36.715
is it numb?

72
00:03:36.750 --> 00:03:39.051
Ask the person to smile.

73
00:03:39.086 --> 00:03:42.688
Is the person's smile
uneven or lopsided?

74
00:03:42.723 --> 00:03:47.359
A - Arm weakness Is
one arm weak or numb?

75
00:03:47.394 --> 00:03:49.861
Ask the person to
raise both arms.

76
00:03:49.897 --> 00:03:52.564
Does one arm
drift downward?

77
00:03:52.600 --> 00:03:56.668
S - Speech Is
speech slurred?

78
00:03:56.704 --> 00:03:58.704
Is the person unable
to speak or hard to

79
00:03:58.739 --> 00:04:00.305
understand?

80
00:04:00.341 --> 00:04:04.176
Ask the person to repeat
a simple sentence.

81
00:04:04.211 --> 00:04:08.647
T - Time to call 911 If
the person shows any of

82
00:04:08.682 --> 00:04:12.417
these symptoms, even if
the symptoms go away, call

83
00:04:12.453 --> 00:04:17.723
911 and get them to the
hospital immediately.

84
00:04:17.758 --> 00:04:20.125
Ischemic strokes are
the most common kind of

85
00:04:20.160 --> 00:04:21.293
strokes.

86
00:04:21.328 --> 00:04:23.462
They can result in
permanent changes to your

87
00:04:23.497 --> 00:04:26.632
life but learning to
recognize the symptoms of

88
00:04:26.667 --> 00:04:29.635
a stroke and getting help
quickly may help you limit

89
00:04:29.670 --> 00:04:32.738
injury and have an
easier recovery.
